2 eggs is 140 to 150 calories
2 toast is 200 calories
Only 500 a day if only 2 eggs. Not enough for an adult.
7 eggs plus 2 toast would work. 1350 calories.
Creatine can be produced by our liver. It’s synthesized from the amino acids (protein building blocks): arginine, glycine, and methionine.

Low intensity exercise burns very few calories per hour though. About 300 calories only. 3 hours of walking around 900 calories. Thats a lot of daily walking to burn off fat.
Calories in and out is 95% right. Nobody knows the whole picture. 1g if fat is 9 calories. 1g of protein is 4 calories. 1g of carbs is 4 calories. But excess carbs spike insulin so body stores more fat. So protein is the best macro.
